OVEN-RACK.

SPEGIFIGATION forming part of Letters Patent No. 556,908, dated March24, 1896.

A uaaan filed Man 11, 1893.

To all whom it may concern:

Be it known that I, J OSEPH STUBBERS, a citizen of the United States,and a resident of the city of Cincinnati, in the county of Hamilton andState of Ohio, have invented certain new and useful Improvements inOven-Racks, of which the following is a specification.

The several features of my invention and the various advantagesresulting from their use, conjointly or otherwise, will be apparent fromthe following description and claim.

In the accompanying drawings, making a part of this specification, andin which similar letters of reference indicate corresponding parts,Figure 1 is a plan view of a rack embodying my invention. Fig. 2 is aplan view of the grate-board detached, the endsecuring sheet having beenremoved. Fig. 3 is a view of one-half of one of the end dies employed insecuring the end-securing sheet or clamp to the bars. Fig. 4 is an edgeelevation of that edge of the upper and lower dies which is at the righthand in Fig. 3. Between the dies is shown one end' portion of theoven-rack immediately after the dies have done their work, the said endportion being broken away from the rest of the rack. Fig. 5 is a portionof one of the end sheets whereby the oven-bars are secured together.Fig. 6 is a section in the plane of the dotted line 6 6 of Fig. 1, thatface of the section being shown which faces toward the bottom of thesheet. This figure is also a section in the plane of the dotted line 8(3 of Fig. 1, that face of the section being shown which faces towardthe top of the sheet. Fig. 7 is aview in perspective of one end portionof the rack-bar, showing a part of the main rod and its angulated end.Figs. at, 5, 6, and 7 are drawn upon a scale eight times larger than therest to secure greater perspicuity in the examination thereof.

A indicates the rack. The bars 13 of the rack are of rod-iron, cut insuitable lengths. These lengths will usually be the same. Each endportion 0 of the bar is bent at right angles to the axial length of thebar. Then I have a bar straight for the most part, and having a shortextension at each end at right angles Serial No. 465,640. (No model.)

to the main straight portion of the bar. The requisite number of bars soformed are now taken and laid in the same plane, one in front ofanother, and another in front of the latter, and so on till all arelaid. The angulated ends of the bars should all point in the samedirection, and these angulated ends are each preferably of a length,beyond the main portion of the bar, equal to the space designed to existbetween adjacent bars of the rack. There is an exception to this, viz: Iprefer to make the angulated ends of the one bar at that side edge whichis uppermost in Fig. 1 shorter, so that the main portion of the bar maybe nearer in line with the adjacent ends of the sheet metal, hereinaftermentioned. The bars, after being put in said position relative to oneanother, are held there by any of the suitable clamping devices, onewell-known form of which is what is termed a jigger D. The upper halvesof such clamps are shown in Fig. l.

The ends of the rack A are each formed of a sheet of metal, as follows:A straight blank is out of a suitable size to fulfill the purposeshereinafter described. This blank sheet A is now centrally folded forits entire length, substantially as shown in Fig. 5. A similar blank issimilarly folded. One of these blanks is now applied to the left-handends of the rack-bars and the other to the right-hand ends thereof. Eachsheet is applied as follows: The lower lap or half, E is slipped underthe angulated ends 0 of the bars B until the fold or creased portion Ecomes in contact with the said ends 0. The upper lap, E, of the sheetwill then overlap the said ends 0.

Each sheet is, as is evident on inspection, made wide enough so that theupper lap, E, and lower lap, E of the sheet when the sheet is placedthus in position will overlap not only the ends C, but the bars B, forashort part of the length of the latter. The sheets being placed inposition, a stamping or compressing device of asuitable construction isapplied to the outer surfaces of the folded sheets-viz., above and belowthe latter-and compression applied. The result is that the sheet metalis bent around the angulated ends 0 and also around the portions of themain bars B adjacent thereto, substantially as shown and indicated bythe letters E ,E and E. The opposite portions of the sheet will meet ornearly so between the bars B.

A convenient die or stamp for accomplishing the foregoing objectconsists of upper and lower dies of like formation. These two dies orhalves being alike,it is unnecessary to show more than one of them, andthis is shown in Fig. 3, and is as follows, viz: In the blank F is agroove running lengthwise of the blank. At intervals to one side of thislong groove branch grooves F are located, and the axial center of eachbranch groove is distant from the axial center of the next branch groovethe distance that exists between the axial centers of the bars B, aboutwhich these particular grooves are to aid in pressing the sheet metal E.

A half-die similar to the one already described is opposite thereto, andthese halfdies are approximated and the sheet metal F and the bars 0 andbars B within said metal, being between the said half-dies, are dulycompacted together and combined in the manner aforesaid. A similar dieconsisting of two such half-dies is at the same time applied andoperated at the other ends of the bars B and upon that sheet of metal Einclosing them and their adjacent angulated ends. Thus the entire rackis simultaneously completed. Such application of such a die isillustrated in Fig. 4.

The rack is obviously very simple in construction, easily and quicklymanufactured, economical of cost, and strong and durable in service.

The wire or rod bars B are cheap of cost, readily out from a longerpiece, and quickly and easily bent so as to have the angulated ends 0.The sheet metal is very cheap, easily cutinto shape without waste, andreadily compressed upon and around the bars, as shown. WVhen completedthe rack is much cheaper than the present rack of cast-iron, every partintegral, and cannot be broken as the cast rack can.

It will be observed that the ends C combine to form a stiffening-rod forthe end of the rack where they'are located, and also perform anadditional, desirable and necessary function to wit, the prevention ofthe sheet metal E from slipping off from the bars 13.

It will be understood that my improvement is useful with variousdescriptions of stoves in fact, is useful wherever a rack is needed inan oven.

My invention is likewise useful as a broiler and is obviously applicablein various ways. which it is unnecessary here to mention.

As the sheet metal of each end of the rack extends toward the center ofthe latter and embraces the bars B for some distance from the ends 0,the metal sheet is firmly held in position and cannot be turned on theends C.

What Iclaim as new and of my invention. and desire to secure by LettersPatent, is

The rack having the bars B and the end portions 0, bent at an angle tothe bars 13. and the sheet of metal E folded at E the ends 0 beingwithin said sheet of metal and adj a cent to the said fold, the adjacentportions of the bars B being between the lips of said sheet. the sheetbeing compressed upon the said bars, the edge of the sheet betweenadjacent bars B meeting or nearly so, and close to or in a plane passingthrough the axial centers of the said bars B, substantially as and forthe purposes specified.
